Forgive me. Me and the metric system don't get along.You mean 2000 IU?
I'm still a Fahrenheit guy.
International units it is. Fortunately they only sell it in IU. The maximum I can get is 1,000 I.U. so I have to take two. I do find it makes a difference.
The claim on the container I have says "Supports a healthy immune system and bone health"
